Answer:
see below
Step-by-step explanation:
Each point moves to half its previous distance from P. It is probably easier to count grid squares on the graph than it is to do the math on the coordinates.
If you're doing the math on the coordinates, it is convenient to use P = (0, 0), then multiply each of the coordinates of A, B, and C by 1/2. For example:
A' = (1/2)A = (1/2)(8, 4) = (4, 2)
Answer:
<h2>4</h2>
Step-by-step explanation:
5k-2k=12
3k=12
k=4
The answer is 12. How did I get it?
< - - - - -- - - - - - - - - - - - - - - - - - - >
A B C
AC = 21 (the whole line adds up to 21)
AB = 9 (half of the line is 9)
BC = AC-AB
21- 9 = 12 so BC is 12
